Page 4: Input Power Requirements
Input Power Requirements SmartGPUs are designed for worldwide use with universal AC input range of 90-264 volts, 47-63 Hz. The GPU is supplied with an input line cord for North American 115-volt AC line service. Therefore, when using 115V power, the GPU should be connected to a dedicated 120 volt AC, 20-amp wall receptacle. For full rated output, an AC branch circuit with sufficient amperage is required. - Page 5 GPU STARTUP: Move the power switch to the ON position. The display sequences through initialization, the White Lightning splash screen, product identification, installed options, and conditions for use. 1. Press the CONFIRM key to accept the conditions for use. 2. If an optional BatteryMINDer maintenance charger (BMC) is installed, select the GPU function to proceed.
- Page 6 Remote GPU Operation For untethered remote indication and control from your mobile device, download the White Lightning SmartGPU App to your mobile device from the Apple iOS Store. (As of this writing, Android support is in development and will be offered in a future software release.) To pair your mobile device with the SmartGPU: 1) Open the SmartGPU app which will search for available SmartGPUs.
- Page 7 When enabled, a countdown of the auto-shutdown timer (ST) will be shown in the upper right corner of the display, alternating with the elapsed time (ET). The countdown timer is shown in yellow until 15 minutes prior to shutdown when it switches to red. Pausing the GPU output or cycling the power switch will restart the timer.
- Page 8 The BLUETOOTH SETTINGS menu includes the following options: START PAIRING This option puts the GPU into pairing mode which allows the mobile device app to “discover” it. Bluetooth pairing uses a numerical passcode which must be confirmed on the mobile device to initiate pairing and connection. DISCONNECT DEVICE Disconnects the current active device from the GPU.
